When asked about her aggressive heckling on the red carpet of the NY screening of her directorial debut, Filth & Wisdom, Madonna downplayed the whole thing.

"It’s a metaphor," Madonna said. "She’s in the Republican Party, I’m in the Democratic Party."

Check out another version of the heckling in which Madonna gets even more passionate about "Sarah f^cking Palin", and goes on demanding to "get that b!tch out of here". The action starts around the 1:40 minute mark.

Metaphor or not, I like the attitude. It goes along well with Madonna’s boxing persona for her Hard Candy album.
